The Impact

Introduction. The incidence of pressure ulcers (PUs) presents a substantial threat to patients, especially geriatric patients, those with restricted mobility, and patients suffering from chronic diseases such as cancer. PUs creates a huge financial burden on healthcare authorities and patients, costing billions to treat and manage. Radiography and radiotherapy patients may experience medical device related (MDR) PUs and studies have shown that high interface pressure (IP) values exist for the head when placed on an X-ray table without a mattress. These high IP values pose a PU risk to patients, especially those accessing prolonged radiography/radiology and radiotherapy procedures. The current study assessed the impact on IP values for the head from using a thin silicone gel surface overlay during radiographic procedures and identified whether this reduced the risk of PUs. Materials and Methods. A calibrated XSENSOR pressure mat was used to measure IP for the head on an X-ray table with and without a thin silicone gel surface overlay. Prior to pressure mapping, the silicone gel surface overlay was assessed for its impact on radiation attenuation and image quality. Results. Study participants were 14 males (70%) and six females (30%), with an age range of 25–53 years (mean = 34.4 ± 7.0). Paired-samples t-test results indicated that there was a statistically significant decrease in the mean IP for the head on the X-ray table without the silicone gel surface overlay (mean = 83.9 ± 8.2 in mmHg) and the X-ray table with the gel surface overlay (mean = 62.4 ± 6.1 in mmHg), p ≤ 0.001 . Paired-samples t-test results indicated that there was a statistically significant decrease in the mean peak pressure index (PPI) for the head on the X-ray table without the silicone gel surface overlay (mean = 205.1 ± 28.2 in mmHg) and the X-ray table with the gel surface overlay (mean = 159.8 ± 26.8 in mmHg), p ≤ 0.001 . Conclusions. The use of a thin silicone gel surface overlay could reduce IP risk for the head by approximately 25%. The reduction in IP risk could have a significant impact in reducing the risk of developing a PU. To ensure maximum benefit, the silicone gel surface overlay should be evaluated to address the specific needs within radiography and radiotherapy planning and treatment settings.

Background: Formaldehyde is a chemical used in several textile production processes, such as hardening of fibers and antimold finishing. However, it has varying effects on humans, such as irritation of the eyes, nose, throat, wheezing, chest pains and bronchitis. In the midst of COVID-19, individuals are using various fabrics for face mask production, which may be containing levels of formaldehyde that can negatively affect their health. Methods: This study investigated formaldehyde levels in fabrics on the Ghanaian market to determine compliance to standards set by the Ghana Standards Authority (GSA) with the aid of experimental procedures. Thirty-two (32) different brands of fabrics were selected for the investigation. Formaldehyde levels were determined using a spectrophotometer (DR6000). Data were analyzed using the Statistical Product and Service Solutions (SPSS) for Windows version 22. The mean performance attributes and the formaldehyde levels of the sampled fabrics were determined before and after washing. Inferential statistics (Analysis of Variance and Paired Samples t-test) at 0.05 alpha levels were used to determine significant differences between and among the groups involved. Results: The fabric samples tested positive for formaldehyde before and after washing, with some exceeding the standard limits set by the GSA before washing. Significant differences existed between and among the samples with regard to formaldehyde levels as well as weight and weave types of the samples and formaldehyde levels. Conclusion: Washing significantly reduced the formaldehyde levels in the fabrics. It is recommended that Ghana standards authority takes a further look at the fabrics on the Ghanaian market to ensure manufacturers comply with set standards and consumers are also advised to wash their clothes at least once before use to reduce the level of impact formaldehyde resin may have on them.

Reasoning Skills

Reasoning skills are very important in encouraging students to think more critically and logically, as depicted in the Malaysian Education Development Plan (2013-2025). Therefore, this study looked into improving the Differentiation Reasoning Level (DRL) of reasoning skills among students for a topic in the Additional Mathematics subject,  known as Differentiation, through reasoning learning strategy. The study participants consisted of a total of 31 students from a secondary boarding school in Johor, selected through a purposive sampling method. A pre-test was carried out for the participants, from the advanced level, followed by a number of repetition tests, before the post-test assessment was conducted. The data collection for this study employed a set of Reasoning Test on Differentiation (RTD) and 10 sets of learning activities on Differentiation based on modified Marzano Rubric for Specific Task of Situations (1992). This dimension involved four types of reasoning skills, namely,  comparison, classification, inductive, and deductive. The survey data, through paired samples t-test, revealed a significant difference between the mean scores in pre-test and post-test (p <0.05). In addition, the paired sample t-test showed a significant difference on the level of reasoning among students from each construct in the reasoning skills before and after using this module. In conclusion, the Marzano Model of Dimensional Learning (1992) is a thinking skill model that can help improve students' reasoning skills. The model covers analysis aspects of what has been learned by implementing the process of identifying reasons, which will help students to add and expand their knowledge. The findings also implied that, the processes of teaching and learning play an important role in ensuring students’ capability to emphasize on the implementation process of reasoning skills
